The ad says "of up to 45%"... Sounds like expensive SNAKE OIL. BTW, you can feed TOO MUCH AIR into an engine, the F/A ratio can only adapt to a certain ratio before degraded performance slaps you in the face. Plus the exhaust can only process so much as well. You could actually ruin your engine over time (especially not having a balanced intake vs vacuum vs backpressure. OK, am I making sense? Like those IAT power boosters ( The ones that 'fool' the IAT sensor ), they just do not work well.
